MIC2920A/29201/29202/29204
General Description
The MIC2920A family are “bulletproof,” efficient voltage regu-
lators with very low dropout voltage (typically 40mV at light
loads and 370mV at 250mA), and very low quiescent current
(140µA typical). The quiescent current of the MIC2920A in-
creases only slightly in dropout, prolonging battery life. Key
MIC2920A features include protection against reversed bat-
tery, fold-back current limiting, and automotive “load dump”
protection (60V positive transient).
The MIC2920 is available in several configurations. The
MIC2920A-x.x devices are three pin fixed voltage regulators
available in 3.3V, 4.85V, 5V, and 12V outputs. The MIC29201
is a fixed regulator offering a logic compatible ON/OFF (shut-
down) input and an error flag output. This flag may also be
used as a power-on reset signal. A logic-compatible shutdown
input is provided on the adjustable MIC29202 which allows
the regulator to be switched on and off. The MIC29204 8-pin
SOIC adjustable regulator includes both shutdown and error
flag pins and may be pin-strapped for 5V output or programmed
from 1.24V to 26V using two external resistors.
